I applied through an employee referral. The process took 2 weeks. I interviewed at Tata Communications (New Delhi) in Jul 2010
Interview
A better hiring process. Two-three round of interviews including HR round. Work culture is better than most other companies. People are good but you have to face few typical leftover Government employee from which this company was taken over by Tata's. Career growth is better if u keep pushing yourself..else you would end up doing same things for over longer period which may stall your growth. Ample opportunity to enhance your knowledge and variety to your career profile.
It was easy.

The interview process for a network engineer typically begins with a phone screening, focusing on the candidate's technical background, certifications, and experience with networking protocols and equipment. A technical interview follows, where candidates solve real-world networking scenarios or problems and may be asked to configure devices or troubleshoot network issues. Questions on routing, switching, security, subnetting, and protocols like BGP or OSPF are common. Some companies include hands-on lab assessments or simulations. The final rounds often involve a behavioral interview to assess teamwork, communication, and problem-solving skills. The process aims to gauge both technical proficiency and cultural fit.

It was a good , but my profile was more like Developer so they rejected me, it was on campus opportunity, first there is online test then technical interviews. overall nice experience,
